Definitions

  • the invention concerns a metal dispensing container, normally known as an aerosol can in which the dispensing valve is crimped into the container. It also concerns the method of making the dispensing container.
  • a dispensing container of the aerosol type of whatever size and nature glass, plastics, etc.
  • the container itself which terminates at the top in a neck and dispensing valve.
  • the distributing valve has to be fixed on the neck of the container so that the product contained is sealed in. It is also necessary for the valve fixing method not to cause any flaws in the external part of the valve which could be seen by the consumer.
  • the valve proper is in the center of a small cup which is inserted in the neck of the container.
  • the cup has an annular external edge which straddles the edge of the neck of the container.
  • the known procedure for fixing the valve cup is to crimp it onto the outside of the container with a clamp.
  • the steps of this method are shown in FIGS. 1-3.
  • the method is commonly used for plastic containers of all dimensions and for medium size metal containers, typically metal containers in which the neck has a diameter of approximately 20 mm.
  • the crimping operation consists of turning in the outer skirt 1 of the cup 2 over the edge 3 of the neck. During the operation, the cup 2 is held on the neck by a force exerted downwardly. By the end of the operation, the seal 4 is thus compressed as shown in FIG. 3.
  • the method normally used to fix the valve is a different one, known as dudgeoning.
  • the valve cup has a special shape, substantially different from that of valve cups which are crimped.
  • the steps of method are shown in FIGS. 4-6.
  • the dudgeoning operation consists of deforming the valve cup 5 outwardly until it is in contact with the inside of the neck 6. By the end of the operation, the seal 4 is thus compressed.
  • dudgeoning is a tricky operation, more difficult than external crimping.
  • dispensing containers with an externally crimped valve cup generally have a better seal than those with a dudgeoned valve cup.
  • This conventional method comprises:
  • valve cup where the part which goes into the neck has an outside diameter substantially equal to the inside diameter of the neck, the outside diameter of the cup of the valve however being slightly less, typically 0.2 mm less, than the inside diameter of the neck in order to facilitate insertion.
  • the first object of the invention is in the sealing of a metal dispensing container in which the neck has a diameter of over 22 mm, wherein the cup of the dispensing valve is crimped onto the container and a clearance or gap of over 1 mm in diameter is present between the inside of the neck and the part of the valve cup which goes into the neck.
  • a further object of the invention is a method of making the dispensing container.
  • FIG. 1 shows the container top portion
  • FIG. 2 shows the container valve unit before crimping.
  • FIG. 3 shows the container valve unit after crimping.
  • FIG. 4 shows the container top portion
  • FIG. 5 shows the container valve unit before dudgeoning.
  • FIG. 6 shows the container valve unit after dudgeoning.
  • FIG. 7 shows the container top portion
  • FIG. 8 shows the container valve unit before crimping.
  • FIG. 9 shows the container valve unit according to the invention.
  • FIG. 7 shows the neck portion of a metal can or container with a neck having an inside diameter at least 22 mm, specifically 25-28 mm.
  • FIG. 8 shows the neck portion, the cup shaped portion of the valved dispensing cap, an annular seal with the components placed so as to leave a radial clearance gap of 0.5 to 1.5 mm between the cup-shaped portion and the neck portion.
  • FIG. 9 shows the neck and cap portions after crimping.
  • the rectangular cross section of the seal is plastically deformed so that the cross section takes the form of an inverted L.
  • Part of the sealing material above the gap is pressed into the gap so as to form the shorter leg of the L-shape.
  • the contacting surface of the sealing material between the metal neck and cup portions is increased and results in the improved sealing effect.
  • the exact shape of the desired sealing material is shown in the figure.
  • the containers are filled with about 20 g of butane gas
  • the containers are stored for 30 days in a ventilated oven at a temperature of 50°
  • the loss is expressed in mg per day of storage at 50°.
  • a prior art dudgeoning process was applied to valve cups on 20 conventional aluminum containers where the inside diameter of the neck was 25.4 mm.
  • the valve cups were of the "dudgeoning" type.
  • the 20 dispensing containers thus obtained were subjected to the seal test.
  • the average leakage rate for the 20 dispensing containers was 30 mg/day.
  • a prior art external crimping process was applied to valve cups on 20 conventional aluminum containers where the inside diameter of the neck was 25.4 mm. The outside diameter of the part of the cups which went into the neck was 25.2 mm. The average leakage rate measured for the 20 dispensing containers was 32 mg/day.
  • valve cups on 20 aluminum containers where the inside diameter of the neck was 26.9 mm.
  • the outside diameter of the part of the cups to be inserted in the neck was 25.2 mm, the same as that of the cups in Test 2.
  • the average leakage rate measured for the 20 dispensing containers was only 10 mg/day.
